SEALING DEVICE

摘要

FIELD: mechanical engineering. ^ SUBSTANCE: sealing device contains a screw cap made of an elastic material represented in the form of a thin-walled pipe with a parallel shank. The parallel shank from the side of a high pressure cavity is tightly closed with a rigid stopper coupled with an axial advance mechanism and fixed in the form of a threaded pair. The screw cap encloses a rigid frame arranged from the side of the stopper with a end partition. The end partition has a through hole. ^ EFFECT: higher accuracy of opening pressure adjustment of the sealing device. ^ 5 cl, 2 dwg
